jilles 9033033601 MFC r260336,r260355: find: Fix -lname and -ilname:
* Take into account that readlink() does not add a terminating '\0'.

* Do not match symlinks that are followed because of -H or -L. This is
  explicitly documented in GNU find's info file and is like -type l.

* Fix matching symlinks in subdirectories when fts changes directories.

As before, symlinks of length PATH_MAX or more are not handled correctly.
(These can only be created on other operating systems.)

Also, avoid some readlink() calls on files that are obviously not symlinks
(because of fts(3) restrictions, not all of them).
